As far as I know, PG assumes, like most C code, that strings don't
contain embedded NUL characters.  The manual[1] has this to says:
 The character with the code zero cannot be in a string constant.

I believe you're supposed to use values of type "bytea" when you're
expecting to deal with NUL characters.
